Simplify the expression. 3 + 2 • (–8) A. –40 B. 40 C. 13 D. –13 Please help me
Alik [6]
We need to follow PEMDAS.

We need to do the multiplication before we can do the addition (which becomes subtraction because of the sign).

3 + 2 • (–8)

3 + (-16)

3 - 16

-13

Your answer is D. -13

Which statement is true? Group of answer choices 8.01 is a smaller increase in sales then 8.001. A debt of $17 is a larger value
Olegator [25]

Answer: The only true statement is:

" A debt of $17 is a larger value than a debt of $20."

Step-by-step explanation:

Let's analyze the options:

A) " 8.01 is a smaller increase in sales then 8.001"

Here you can see the difference:

8.01 - 8.001 = 0.009

The difference is positive, then 8.01 > 8.001.

Then as we are talking of increases in sales, the numbers are positive, then we have that 8.01 is a larger increase in sales than 8.001.

B) "A debt of $17 is a larger value than a debt of $20."

A debt is written as a negative number, then:

A debt of $17 is written as -$17, and a debt of $20 is written as -$20.

Then -$17 is a smaller negative number than -$20

-$17 > -$20

Then this statement is true.

C) " 2/3 bellow zero is lower than 6 bellow zero"

ok, 2/3 bellow zero is: -2/3

6 bellow zero is: -6

-2/3 is larger than -6

-2/3 > -6

then -6 is lower than -2/3, the statement is false.

D) "1/2 of an apple is equivalent to 8/4 apples"

Well, here you can do the quotients:

1/2 = 0.5

8/4 = 2

So these numbers are not equivalents.
